Hey Product Hunt! 👋
I'm an indie dev, and Sugilite started as the notes app I wanted for myself. I write everything in Markdown and keep it local — plain files in a folder, no database, no account, no cloud. But I also live in AI tools all day, and I kept hitting the same wall: my notes and my AI couldn't talk to each other without me copy-pasting back and forth.
So I built that bridge in. Sugilite ships with a standalone Model Context Protocol (MCP) server — think of it as a USB-C port for AI. It runs even when the GUI is closed. Point Claude, ChatGPT, Cursor, Gemini, Windsurf, Antigravity, or any MCP-compatible client at your vault, and your notes become tools the AI can actually use: search them, read them, write new ones, follow links, pull related notes. "Find what I wrote about pricing last month and draft a follow-up" works against your real notes, no glue code.
A few things I care about:
- Standalone MCP server, in the box. No plugins, no extra install — just one config snippet (the first-run card hands you one to copy-paste).
- Semantic search by default. Find a note by meaning even when it shares no words with your query — fused with exact keyword matching so precise terms still win when they should. All on-device.
- Embeddings run fully on-device via a bundled EmbeddingGemma model. No API keys, nothing sent to the cloud, and it's multilingual.
- Already using Obsidian? No migration. Point Sugilite at your existing vault and start — frontmatter, [[wikilinks]], ![[embeds]], daily notes, templates, and CSS themes all carry over.
- It's just Markdown. Plain files on your disk: wikilinks and backlinks, a related-notes panel, a force-directed knowledge graph, a 2D vector map, calendar/timeline views.
macOS (Apple Silicon) and Windows (x64), and it's free. This is v0.0.40 and very much a one-person project, so I'd genuinely love your feedback — especially which AI client you'd point at it first. I'll be in the comments all day.
